It's Paris, 1962. Wealthy stockbroker Jean-Louis lives a staid and bourgeois existence with his perfectly-presented socialite wife. But when the family's maid abandons them, into the residence comes Maria, who is young, hardworking and - quelle horreur! - Spanish. Remarkably it does not take long for the entire building to become enchanted with the new arrival; Maria rallies the friendships of the other servants on the sixth floor and soon Jean-Louis is swept up into their wild and fun-loving world.
